The box of Rock gets you great sounding Marshall tones regardless of your amp, however for best results it obviously sounds most like a JTM45 through an actual Marshall. You can get a wide variety of distortion tones from crunch to overdrive to heavier distortion. This can be further modified by your volume knob . You can use the boost knob in conjunction with the distortion for an extra kick, or as a stand alone boost. Low current draw (3mA) so it should last ages on a battery!
